$Y$TEW=1 FOR VENTBLATENG CARS.

Application filed arch To aZZ whom it may concern:

Be it known that I, GEORGE HENRY LAYNG, I a subject of the King of Great Britain, residl ing in.the city of Torontofin the county of York, in the Province of Ontario,; Canada,

new and useful Imrovements in Systems for Ventilating Oars, l of whichthe following is a specification.

My invention relates to improvements in systems for ventilating cars; and the objects of my invention are, first, in connection with passenger-cars to dispense with the top win- 1 reduce cost of construction and cost of main-- tenance of same; secondly, to provide perfect ventilation in all classes of cars without causing a downdraft on the heads of the passengers and without the possibility of smoke entering into the cars and Without the necessity of having to open the side windows, and, thirdl to keep the top of the car cool even thong the car may be stationary; and in providing the car with a false ceiling, t us making a space substantially for the whole len th of the car, between said false ceiling and t e roofofthe car, with which s ace communicates one or more pipes or con uits for conducting air-thereinto and therethrough, constructing the false ceiling with apertures, if desired, through which air will pass from the body of the car, and providing one or more conduits or pipes whereby fresh air is fed into the body of the car and below said false ceiling, and details of construction, as hereinafter more particularly explained.

Figure 1 is a longitudinal vertical section through a passenger-car, showing a suitable construction whereby In invention may be put into ractice; and ig. 2 is a horizontal cross-section on the line a b, Fig. 1.

In the drawings like characters of reference indicate corresponding parts in each figure.

It is well known'that it is a great desideratum to ventilate cars of all classes, whether they be passenger-cars or refrigerator or fruit 'cars. Particularly in connection with the convenience of passen ers on railroads it is desirable that the coaches be thoroughly and conveniently ventilated. In the drawings herewith I show and describe a' suitable construction whereby my invention may be put into practice in connection with'passener-cars, and by one skilled in this art it will Specification of Letters Patent.

14,1906. Serial No. 306.017.

e understood that my invention can be Patented Nov. '27, won

readily applied to the ventilation of fruitcars, refrigerator-cars, and, in fact, all classes of cars or coaches on railroads.

The car A is provided with any suitable false ceiling B, which, together with the roof O of the car, forms a space D therebetween, with which communicates one or more pipes or conduits E and E, whereby fresh air passes into and out of said space D. Although the car may be stationary, it will be understoodthat as the pipes or conduits E and E are freely open, air will be circulating therethrough and through the space D, thus keeping the roof of the car cool. For illustrating purposes I am supposing that the car A is traveling in the direction indicated by arrow. Asa result of the speed of the car,'it Will be understood that a very strong draft is passing through the space D. Now in order to provide ventilation in the body ofthe car be low the false ceiling B, I provide one or more conduits F, which communicate with the outside of the car and at both ends, as shown. In order to prevent air passing right through the conduit and not entering into the car therefrom, I provide any suitable valve or damper for that purpose. According to the construction shown for this purpose I rovide the valves or dampers G and G, w ich are similarly constructed to those used in hot-air pipes leading from a furnace. As the car is moved in the direction indicated by arrow, it will be understood that the valve or damper G must be closed, thus preventing the air from passing directly through the conduit F and compellin it to pass therefrom through the series of holesf formed therein and preferably more on its upper side. When the car is rno ving in this direction, it will of course beunderstood that the valve or damper G is left open. It is well known that the foul air in the car will rise forcing the fresh air through the conduit F into the car and providing the false ceiling B with suitable apertures the foul air is uickly carried through 1: e space D and passes therefrom through the conduits E.

I prefer to make the apertures H in the false ceiling B so that I can control same. According to the construction shown for this pu ose I pivot in the false ceiling Band in sai apertures slats I of any suitable con struction,which are linked, as shown at L, to the rod M, which is held so as to have suitable bearing in the walls Q of the car. By

to the top thereof. Now bysaid apertures into means of any suitable arm or lever N, pivoted in the false ceiling B and suitably connected, as at O, to the rod M, so as to permit of the necessary relative movement between these parts, it will be understood that the slats I are operated to regulate the size of the apertures II. The slats I are preferably slanted, as shown, when the car is moving in the direction indicated by arrow.

By means of any suitable hoods e the extreme ends of the conduits or pipes E and E and F are more or less shielded, so as to prevent as much as possible the entrance into the car of sleet, rain, or smoke.

I have shown a sleeping-compartment U, in the car, and by inspecting the drawings it will be seen that the conduit F passes therethrough and that the false ceiling B extends through said sleeping compartment, thus providing perfect ventilation of same.

In order to reduce to a minimum the injurious action of any drafts around the lamps (not shown) for-lighting the car, the false ceiling B is constructed, as shown at V,

above where the lamps may be placed, without any aperture. s

It will of course be understood that when the car is moving in the direction 0 posite to that indicated by arrow that the amper or valve Gwill be closed and the damper or valve G opened and that the slats I will be moved in the opposite position to that shown.

What I claim as my invention is- 1. In a system of the class described, the combination with a car and the roof thereof, of a false ceiling placed in said car so as to provide between same and said roof 'a space, and provided with a ertures to permit air to pass into said space rom the body of the car; conduits or pipes for controlling the assage of air into and out of said space, an a conduit or pipe for conveying air into t1 3 body of said car below said false ceiling.

2. In a system of the class described, the combination with a car and the roof thereof, of a false ceiling placed in said car so as to provide between same and said roof a space, and provided with apertures; means for controlling the opening and closing of said apertures; conduits or'pipes for controlling the passage of air into and out 'of said space, and a conduit or pipe provided with apertures whereby air is introduced into the body of said car below said false ceiling.

3. In a system of the class described, the combination with a car and the roof thereof, of a false ceiling placed in said car so as to provide between same and said roof a space, and provided with apertures; means for controlling the opening and closing of said apertures; conduits or pipes for controlling the passage of air'into and out of said space; a conduit or pipe provided with apertures whereby air is introduced into the body of said car below said false ceiling, and means for controlling the passage of air through said conduit.

4. In a system of the class described, the combination with a car and the roof thereof, of a false ceiling placed in said car so as to provide between same and said roofa space, and provided with apertures; a plurality of slats o crating in said apertures so as to open and cfbse same; means for operating said slats; conduits o pipes for controlling the passage of air into and out of said space; a

conduit or pipe provided with apertures whereby air is introduced into the body of said car below said false ceiling, and means for controlling the passage of air through said conduit.

5. In a system of the class described, the combination with a car and the roof thereof; a false ceiling, provided with apertures or openings, in said car and below said roof so as to provide an airspace therebetween, and conduits or pipes controlling passa e of air into and out 0 said space, of a con uit provided with openings or apertures so as to deliver fresh a1r into the body of said car and below said false ceiling.

6. Acar-bodyfor passenger-cars constructed without windows in any portion of the roof and provided with a false ceiling, and further provided with openings controlling the passsage of air into and from the space between the roof and said false ceiling.

Intestimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
